Embodiments also describe a kind of turn-sensitive device system in Fig. 1, this turn-sensitive device system is for determining the rotation return position of timing belt pulley 38 and 44 relative to the fixed target in bevel head attachment 10.In the embodiment shown in fig. 1, turn-sensitive device system comprises: the turn-sensitive device target 72 connected with inclination timing belt pulley 44, and this turn-sensitive device target rotates around rotation 12 together along with inclination timing belt pulley; Turn-sensitive device 74, this turn-sensitive device is arranged on fixing Angle Position around rotation 12, for cooperating with turn-sensitive device target 72.Turn-sensitive device 74 can be proximity switch, such as inductive proximity switch, is connected with motor controller 70.Once perform the inclination return described by the preceding paragraph, rotate return just by making rotation drive motor 34 and inclination drive motor 42 run and be achieved simultaneously, thus make rotating timing belt wheel 38 and inclination timing belt pulley 44 combine rotation, until turn-sensitive device target 72 makes turn-sensitive device 74 trip, to stop motor in rotation return position.
Although Fig. 1 does not show, bevel head attachment 10 can be arranged on the bracket of CNC cutting machine.The portal frame that this bracket can be suitable for transversely advances to opposite side from side, and portal frame can be suitable for moving along the longitudinal direction of the cutting bed of cutting machine.Bevel head attachment 10 can comprise lifting driven unit, this lifting driven unit for by the main support member of attachment arrangement 10 relative on the installing plate of attachment arrangement 10 raise and reduce, this installing plate is suitable for making attachment arrangement 10 be attached to cutting machine bracket regularly.This structure does not show in the schematic diagram of Fig. 1, but can see in another embodiment relevant to Fig. 2.
As shown in Figure 1 shown in meaning property, rotation drive motor 34 and inclination drive motor 42 are connected with CNC controller 70, for manipulating the operation of rotation drive motor and inclination drive motor.Motor controller 70, by being stored in the software instruction programming on built-in storage or external memory, driving order with the respective motors calculated for rotation drive motor 34 and inclination drive motor 42, thus realizes the expectation tiltangleθ of cutting torch.The tiltangleθ expected is assigned in cutting process, is input in controller 70 by cutting process, or utilizes cad file automatically to generate by third-party application software and be loaded in controller 70 by the user of operation user interface.Figure 1A schematically describes tiltangleθ, this inclination angle and rotation 12 about and relevant with the cutting planes P perpendicular to rotation 12.Calculate motor driving instruction with make the torch axis TA of the inclination angle place cutting torch of specifying and rotation 12 coplanar.According to the present invention, motor controller 70 programming utilizes only two kinds of transformation equations to calculate respective motors and drives order.These two kinds of transformation equations depend on the angular relationship between tilt axis 28 and rotation 12, the sharp angle α especially between tilt axis 28 and rotation 12.These two kinds of transformation equations can be expressed as follows:
β=InvCos(((Cosθ–1+(CosФ)
2))/(CosФ)
2)
ω=InvTan((SinФ-(SinФ*Cosβ))/Sinβ)
β is the pilot angle rotated around tilt axis 28, and ω is the pilot angle rotated around rotation 12, and θ is the inclination angle expected, and Ф is the supplementary angle (i.e. Ф=90 °-α) of sharp angle α.According to non-limiting example, the sharp angle α formed between tilt axis 28 and rotation 12 is 60 °, transformation equation can be expressed as follows:
β=InvCos((Cosθ–0.25)/0.75)
ω=InvTan((0.5–(0.5*Cosβ))/Sinβ)
Respective motors order can perform simultaneously, to maintain torch axis TA and rotation 12 is coplanar in perpendicular, as shown in Figure 1A.Above-mentioned transformation equation and the tiltangleθ of specifying do not comprise transmission ratio for each respective drive system and belt wheel ratio.In rotary course in the present embodiment, the pass between inclination timing belt pulley and rotating timing belt wheel is 1:1, but motor relation may be different, depend on transmission ratio and belt wheel ratio.
Advantageously, the invention provides a kind of configuration, wherein, tilt axis 28 and rotation 12 are just crossing in the most advanced and sophisticated below of cutting torch T.This configuration can make cutting torch tilt and utilize only two kinds of rotations to rotate around constant tool point or focal point F.If tilt axis 28 is arranged to perpendicular to rotation 12 and just crossing in the most advanced and sophisticated below of cutting torch T with rotation 12, so tilt axis 30 and inclined arm 26 will disturb workpiece.In the configuration of prior art, tilt axis is arranged to vertical with rotation, and is positioned at the most advanced and sophisticated top of cutting torch, but this is configured in the process tilted around tilt axis the translation that cutting torch tip can be caused relative to workpiece.Such transfer is unacceptable, in order to eliminate this translation, needs the extra transformation equation that the X, Y, Z axis on machine bracket is moved.This relates to more complicated software programming, and the accuracy at inclination angle will depend on the accuracy of 5 axial-movements, instead of depends on the accuracy that two axial lines provided by the present invention is moved.
As will be realized, the present invention includes a kind of for controlling the method for cutting torch T-phase for the tiltangleθ of cutting planes, the method comprises the steps: to limit the rotation 12 perpendicular to cutting planes; Limit the rotation forming sharp angle α with tilt axis 28; And make cutting torch T around rotation 12 and rotate around tilt axis 28, thus obtain the expectation inclination angle of cutting torch, with make torch axis TA and rotation coplanar.Motor 34 and 42 can be driven according to the transformation equation of above-mentioned instruction simultaneously, thus cutting torch is rotated around rotation and tilt axis simultaneously.This keep in the adjustment process at inclination angle torch axis TA and rotation 12 coplanar.
